Temperature should be around 70-80, ph around 5.5, bubbler in reservoir, peroxide and higher % IBA, kelp. I bundle 10-15 cuttings together light cycle 24hrs. Various cuttings callus in 2 -3 days, root on 5-7 days vs 2-3 weeks. They waterpump usually provides enough heat. Good luck

Do you put peroxide and IBA in the water of your system and what kind of IBA are you using?

I did use both. peroxide maybe 1/4 cup per two gallons every 3-4 days, IBA was dip-n-grow, only put in at the outset. At the time, I couldn’t find good references for using IBA in a soiless system, so I think I applied it to the stems, then dumped the extra in the circulating water.

I dilute powder in alcohol, then water and only use a tiny bit. Forget right of hand, but I use a tinny measuring spoon provided. Total liquid is 4..4-5 gal
